IBM Personal Computer AT Manual To Operations page 293

Introduction
to Testing
Testing begins with "Test 100" and ends with the
"System Checkout" screen. Tests are run only on the
options you have attached to your IBM Personal
Computer AT. This manual however has tests for all
the options that are available for the IBM Personal
Computer AT. If your manual has an option not
displayed on your screen, go to the next test in your
manual. To match the test on the screen with the test
in your manual, look at the bottom of the page in this
section. The page number will be the same as the test
you have on the screen.
